Abstract

Techniques and tools for code table selection and joint coding / decoding of macroblock mode information for macroblocks of interlaced forward-predicted frames are described. For example, a video decoder decodes a variable length code that jointly signals macroblock mode information for a motion-compensated macroblock. The jointly signaled information includes a macroblock type, whether a coded block pattern is present or absent, and whether motion vector data is present or absent for the motion-compensated macroblock. A video encoder performs corresponding encoding.

Description

COPYRIGHT AUTHORIZATION A portion of the disclosure of this patent document contains material which is subject to copyright protection. The copyright owner has no objection to the facsimile reproduction by anyone of the patent disclosure, as it appears in the Patent and Trademark Office patent file or records, but otherwise reserves all copyright rights whatsoever. TECHNICAL FIELD Techniques and tools for interlaced video coding and decoding are described. For example, a video encoder and decoder use code table selection and joint coding / decoding of macroblock mode information for macroblocks of interlaced forward-predicted fields. BACKGROUND Digital video consumes large amounts of storage and transmission capacity. A typical raw digital video sequence includes 15 or 30 frames per second. Each frame can include tens or hundreds of thousands of pixels (also called pels), where each pixel represents a tiny element of the picture. In raw form, a computer commonly represents a pixel ...
